dog wont poop outside

Question
we just adopted a 1 year old terrier mix from our local shelter. he has no problem going pee in the back yard or going poop on our walks... but has only pooped in our back yard 2 times in the month and a half that he has been with us. we have tried pee pads, moving the pee pads closer to the door, moving the pee pad with poop outside, moving just the poop outside, correcting him when caught in the act, interrupting the act and taking him outside, and a spray to make him want to go in a certain area, a carpet cleaner that gets rid of the smell, my husband even ran/ walked him around the backyard for almost 2 hours trying to get him to go. when his does go either pee or poop outside whether on a walk or in the back yard he gets praise. he will poop in the house in the few spots where the pee pads were. currently we are not using pee pads and just clean it up. my only other idea is to chain him up outside till he goes. but im afraid that he will regress like when we would walk him around the back yard trying to get him to poop ( he started peeing in the house again)

Answer
You are on the right track with running him around the back yard and lavishing praise on him when he does go.  Inside, when you are around you need to keep a close eye on the dog. Use closed doors or gates to keep it in the same room as you are, and perhaps as I do, a short chain fastened to the computer desk. If you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out. When you can't watch it, crate it.

It is only natural that a puppy resists its crate at first. What the puppy wants more than anything else is to be others, you, anyone else in the household, and any other pets. In our modern society, even if we are home, other things distract us from the attention an uncrated puppy must have. The only real solution is to crate the dog when you aren't around. The dog may be happier in its den than loose in the house. It relaxes, it feels safe in its den. It rests, the body slows down reducing the need for water and relieving its self. Dogs that have been crated all along do very well. Many of them will rest in their crates even when the door is open. I think the plastic ones give the dog more of a safe, enclosed den feeling. Metal ones can be put in a corner or covered with something the dog can't pull in and chew. Select a crate just big enough for the full grown dog to stretch out in.

Leave it some toys. Perhaps a Kong filled with peanut butter. Don't leave anything in the crate the dog might chew up. It will do fine without even any bedding. You will come home to a safe dog and a house you can enjoy.

A dog that has not been crated since it was little, may take some work. Start out just putting its toys and treats in the crate. Praise it for going in. Feed it in the crate. This is also an easy way to maintain order at feeding time for more than one dog.

I encourage people to adopt dogs, but sometimes there are problems.  It may take a little time, but you should be albe to solve this one.
